Why don't things fall up?
Gravity comes from the Earth.
Everything is pulled toward the Earth.
because the Earth is so big.
It keeps us grounded
to the earth.

in space?
How would
you sleep with
less gravity?
Gravity pulls everything equally.
Big or small?
Heavy or light?
Remember our experiments.
Yes!
The sun's gravity
is stronger than the
Earth's because the
sun is bigger than the
Earth.
This force, gravity,
keeps the Earth in
orbit around the sun.
